Famous quotes containing the word valleys:

    “It was a comfort in those succeeding days to sit up and contemplate the majestic panorama of mountains and valleys spread out below us and eat ham and hard boiled eggs while our spiritual natures reveled alternately in rainbows, thunderstorms, and peerless sunsets. Nothing helps scenery like ham and eggs.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)
